oon-rims.

Be it known that I, CHARLES E. Nu'r'rrn'e, a citizen of the United States, and resident of Hopedale, county of Worcester, State of Massachusetts, and whose po'st-ofiice address Massachusetts, have invented an Improvement in Loom-Frogs, of which the following description, in connection with the accompanying drawing, is a specithe drawingirefpresenting like parts. V

This invention relates to a loom frog such as employed in the protector mechanism for looms.

The object of the invention is to provide a construction in which a helical wire coinand preferably a pair of such springs, is provided to take up the blow on the loom mechanism acts, thus eliminating the use of rubber buffers which deteriorate, wear and are liable to get out-order;

The object of the invention is also to provide a loom frog in which the parts including the springs may be readily assembled'and in which the correct position of the springs is insured at all times.

These and other objects of the invention will appear more fully from the accompanying description and drawings, and will be particularly pointed out. in the claims.

In the drawings Figure 1 is a view in side elevation of a portion of a loom showing the frog with the invention embodied therein.

F ig, 2 is an enlarged detail taken in cross section on the line 2/2 of Fig. 3.

Fig. 8 is a side elevation of a portion of a loom frame showing the frog in position, and with the parts partially in vertical section to expose the springs.

Fig. t is a view similar to Fig. 8 showing the'frogin the position to which it is moved upon the actuaton of the protector mechanism.

Fig. 5 is a topplan view partiallybroken away of the construction shown in Fig.3.

The protector mechanism for a loom by means of which the loom is stopped when a shuttle fails to boxed is a well known and common mechanism and in a simple form is illustrated in the patent to Draper No. 911,219, granted Feb. 2, 1909.

This protector mechanism usually" in- Application filed. June 13, 1919.

7 both sides of the loom a part which is known as a frog and which. is slidingly mounted upon the loom frame. In case the shuttle fails to'boX, or is improperly boxed atthe end of the lay, cerit isunnecessary to illustrate or describe, is brought intoplay which causes a dagger attached to the lay to drop into the path of aprojection on the so that, as the lay, beats up, the dagger strikes the frog and carries, it forward thus actuating mechanism which stop. This mechanism is of a well known and familiar type and as the presest invention relates to but a single featureit need not further be described. i

In the preferred construction illustrated, the frame 1 at one side of the looni'is shown as provided with the usual shipper standwhich it occupies When the ship will swing laterthrough suitable when the loom is running. per 18 thrown rearwardly it into the recess 3 and connections shift the belt from'the fast to the idle pulley or otherwise act to stop the loom.

A horizontal portion t of serves as a frog support ingly mounted the frog 5. This frog is recessed at 6 opposite to the support a and is guided in its sliding movement in any suitable manner. For that purpose the forward end of the frog is shown as bifurcated at 7 and straddling the upright portion 8 of the loom frame, while at its rear end it is again the loom frame bifurcated. at 9 and fits over a block 10 secured by a bolt 11'to the loom frame.-

A thrust member 12 is seated in therecess 6 of the frog on the support at and abuts such upon which'is slidas the projection 13 from the support 4:.

This thrust member is shown as havnig a flat base restingon the support and an up standing flange 14k. Projecting from this flange 14 of the thrust member are a. pair of centeringconically pointed projections 15. A pair of helical wire compression springs in the recess 6 of the frog, and each of the springs fits at one end over one of the centering points 15 andabuts against the thrust member 12 and at the opposite end abuts. against the inner surface or wall 17 of the frog. The centering points thus serve to position the helical springs and hold them in place. In addition, the frog is 7 provided With a separating rib 18 depending from the 'Wall of the recess opposite the support and between the spring 16 and this rib position and support the further acts to springs.

It Will thus be seen that a very strong and 7 simple: construction is provided, the parts of Which may be readily assembled in position' on the loom, and one in whlch a heavy .co'mpression may be readily provided. The

springs are protected by the frog and Will last indefinitely;

of centering Inlthe operation of the protector mechanism the improper boxing ofthe shuttle, or the failure of the shuttle to box, causes the dagger 19 to drop into the path of the frog. As the la beats up,- the dagger. strikes against a ardened plate, not shown, supported by theshoulder 201mm moves the frog forward by compressing the springs 16. This movement of the frog through suitable means not shovvnv actuates the shipper to.
